COIN CONTROLLED ACTUATING DEVICE Filed April 14. 1932 Patented Nov. 3, 1932 NET GEORGE A, LONG, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE GRAY TELEPHONE PAY STATION COIJIFANY, OF HARTFORD, CONNECTICUT, A CORPORATIONv OF CON- NEC'I'ICUT Application filed April 14,

My invention relates to devices the operations of which are controlled by means of falling coinsand an object of my lIlVGl'ltlOIl, among others, is the provision in a devlce of this type of means for preventing fraudulent operation by means other than that of a coin.

One form of a device embodying my invention and in the constructon and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing, in which- Figure 1 is an isometric view on enlarged scale of a portion of a'coin controlled telephone apparatus embodying my improvement.

Figure 2 is a view, scale still further en-- larged, illustrating the connection between the trip and the switch lever.

lVhile my improved device is not limited in its use to a mechanism of any particular type, .yet, as it finds ready adaptation in the operation of coin controlled telephone apparatus I have shown it in the drawing herein as embodied in such a mechanism. In apparatus of this type as heretofore constructed it has been possible to release certain members of the mechanism by jarring blows, or a succession of such blows applied to the case containing the mechanism, and such fraudulent use has frequently been made use of to obtain service without the payment of a toll or fee therefor.

My improved device illustrated and described in the drawing herein is provided with means whereby such fraudulent operation cannot take place, in such drawing the numeral 4 denoting a switch controlled frame, preferably of U-shape, pivotally mounted on the upper end of a supporting post 5 rising from an electromagnet arrangement as commonly employed in apparatus of this sort, and for which reason a detailed description of such mechanism is omitted herein. The frame 4.- has a coin actuating finger 6 projecting from one side thereof into a slot 7 in a coin chute 8 having a hopper 9 into which a coin is directed in the operation of the device. A trip 10 in the form of a projection from an upper side part of COIN CONTROLLED ACTUATING DEVICE- 1932. .Serial No. 605,177.

device I form an mwardly curved edge 15 on the upper end of the trip, this curve being preferably on the arc of a circle, the center of the arc being preferably on a line passing centrally through the trip 10, and as shown in Figure 2 of the drawing. I also provide a roller 16 pivotally mounted on a stud 17 projecting from a laterally bent end 18 of the lever 11, and as shown in Figure 1 of the drawing.

The mechanism is somewhat delicate -in its construction, the weight of the coin onthe finger 6 being sufficient to overcome the weight of the frame 4 thereby tipping the latterupwardly to release the trip 10 from the lever 11. The weight of the frame 4: is, however, sufficient to return the frame to its normal position when the coin is released from the finger 6. Similarly while the resistance of the spring 19 is sufficient to retain the roller 16 in contact with the indented end 15 of the trip, this resistance is not sufficient to prevent the trip from being readily disengaged from the lever'll by the weight of a coin.

From this it will be seen that if the frame 4: be moved, as by a jar, to displace the roller 16 from the center of the indentation in either direction, the roller will at once return to its mid-position and it will therefore be impossible, by a succession of jars, to dislodge the roller from the indented edge of the trip and thereby release the lever 11.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof, but I desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim:

1.- A coin actuated device including a movably mounted switch actuating member, a movably mounted frame including a coin actuated finger, and atrip having an indented edge comprising a rest at the end thereof for said switch actuating member. M g

2.- A coin actuated device including a movably mounted switch actuating member pressed into contact with a trip, a movably mounted frame including a coin actuated finger, and a trip on said frame having an indented edge comprising a rest for said switch actuating member at the end thereof.

3. A coin actuated device including a movablyinounted frame, a' coin actuated finger projecting from said frame, a trip borneby said frame and having an indented edge, and

a movably mounted switch actuating frame comprising a lever having its end supported in said indented edge of said trip.

' A coin actuated device including a movably mounted switch actuating member havinga laterally bent end, a movably mounted frame including a coin actuated finger and a trip having an indentededge, and a projection 'froini said bent end resting in the indented edge of said trip.

" 5. A coin actuated device including a movably mounted switch actuating member having a laterally bent end, a roller rotatably mounted on said bent end, a movabl-y mounted frame including a coin actuated finger, and

v. a trip having an indented edge within which said roller is adapted to rest.
